Because 2t burns cleaner than 4t.
If it is a 2-stroke engine, 2-cycle engine oil is added to the gasoline. If the engine is 4-stroke, regular 30W motor oil is used. To tell if your engine is 2-stroke or 4-stroke, look for a spout where oil is poured into the engine. If there is no spout, then the engine is 2-stroke and 2-cycle oil must be added to the gasoline.
yes for a 2 stroke engine.
The best way to know if an engine is 2-stroke or 4-stroke, is to look for an oil spout. If the engine has an oil spout where oil has to be poured into, it is a 4-stroke. If the engine has no oil spout and the oil has to be added to the fuel, then it is a 2-stroke.
There is no difference between 2 stroke oil and 2 cycle oil. They are the identical product but are called different names. The 2 stroke refers to the engine type that the oil can be used in.
It is possible to use 4-stroke oil in a 2-stroke engine in an emergency situation. You should not use this oil in the long term as it will damage the engine.
A 2-stroke engine requires adding 2-cycle oil with the gasoline.
It depends if it is a 2 stroke or a 4 stroke. A 2 stroke engine, you mix the gas and oil. A 4 stroke engine, there are separate tanks for the oil and gas.
No you can not.
Drain it out and replace with proper oil
Oil is a lubricant. 2 stroke oil is designed to be mixed with gasoline and in that form it lubricates the engine. 4 stroke oil lubricates the engine but is not burned as 2 stroke oil is. This has nothing to do with speed. So, the answer to your question is neither is faster as they are just lubricants.
if your scooter has a engine oil dip stick then it is a four stroke. if it has a oil tank that you have to put oil in then it is 2 stroke.
If the Ryobi is a 2 stroke engine you must use 2 stroke oil and never use 4 stroke. But you ask about 20w50 oil which is confusing. 2 cycle engine do not use multi-vicosity oil. Any 2 cycle oil can be used in your Ryobi if it is mixed at the correct ratio.
